I really, really liked the original Wulong Cha, even though I would have found the scent more appropriate in a luxurious spa than on skin. I don't dislike this X version either, but I couldn't use the words "I like it a lot" with a clear conscience.
The two Wulong-Cha's don't seem that similar to me. In Wulong I, the cubeba litsea covers everything from my perspective, sending the tea somewhere in the back. By contrast, in Wulong II, the green tea note is obvious even to me, and the litsea is barely noticeable, dominated by bergamot at the top of the pyramid. The main battle is between the green tea and the white magnolia (that easily recognizable magnolia accord once you've repeatedly smelled perfumes that list the note, but which has not the slightest connection to the real magnolia). I don't know if in this case it's the happiest of combinations, it seems to me that the tea somehow turns the magnolia sour and that's not exactly ideal.
At first glance, it vaguely reminds me of two other perfumes, and the two are neither the original Wulong nor Green Tea, but Magnolia en Fleurs (Avon) and Amyris Femme (MFK). Somewhat ironically, my favorite of the three is the outsider Magnolia en Fleurs.
